Summary

I think, the original is a really well designed fidget from ordinarycontraptions :-)

Only problem was, that it doesn't fit well in my hands because it's very short, although it's already thick enough. It wouldn't make sense to scale it up only. So I created a 60mm longer version (when it's opened). I also changed the blade, so that it will be a bit sharper!

In one of the posted pictures You see my version together with the shorter original.

Post-Printing

When Your printer isn't well calibrated, it may be necessary to sand the parts a little bit. Instead of that, You could also try the CURA setting "horizontal expansion=-0.2 " printing the core part.
